Love what Automile are doing, I'm really interested in diagnosing car issues myself, and it also looks like they have a solid B2B model for managing fleets of cars.
They have just released a 2nd generation device, and you can apply to get one for free, just visit the following announcement.

@leonpals@jcvangent Whenever you connect Automile to a new car it will add it to your account and remember to store the data belonging to that specific vehicle. This means you can move around your device and it will keep data stored to the right vehicle. @sunekaae is a great example, he tried using Automile when renting different cars at Zipcars. We also provide a nice integration to Carfax to lookup more information about your car.

@arjunram@automatic@mattlanham The main difference is that Automile works in 53 countries using all local carrier networks (GSM). In US it uses AT&T and T-Mobile to provide free roaming with a super tiny protocol that reduces data overhead. It also have a high resolution GPS receiver and the phone is never needed to constantly provide data around your car.

I currently use @dashmobile and @automatic. How different is this? Can I have access to raw car data with @automile?
Dash is a free app that works with any OBD2 sensor off of eBay ($10)
Automatic is a free app that works only with it's proprietary sensor ($100)
Automile?
One difference I notice is that this has inbuilt 3G (so connected to cellular network, so subscription fees are necessary)
